Yandeloid

Yandeloid, a combination of the terminology Yandere and Vocaloid, pertains to Fanmade Vocaloids representing mentally unstable traits, such as being initially very loving and gentle to someone before their devotion becomes destructive in nature, often through violence. The Japanese term is derived from the words yanderu (病んでる) meaning a mental or emotional illness and deredere (でれでれ) meaning to show affection.

Depiction
Yandere Vocaloids are commonly depicted covered in bandages and holding some kind of object to be used as a weapon. It's not unusual to see them covered in blood, be it their own or their latest unfortunate victim. And while they tend to be wide-eyed and pale skinned when shown unstable, most are seen with an eerily calm expression.

They hold a great admiration for their master (creator) and will show violent tendencies if their master acknowledges other Vocaloid, or if another Vocaloid appears to be getting too close. The same action will be done if they currently have a crush on another character such as another Vocaloid.

History
The early appearance of Vocaloids with yandere traits appeared in 2007 a few weeks after the release of Hatsune Miku, a Crypton Future Media Vocaloid 2. While many images being produced simply involved Miku, the popularity of Yandeloid picked up in February 2008 and continued onward.
